[Rheumatological complications of immune checkpoint inhibitor therapy]

Cancer management has been revolutionised by immune checkpoint inhibitors. Their use and indications increase in parallel with the recognition of their various side effects. Arthritis, myositis, and vasculitis are among the most common rheumatologic immune-related adverse events (irAE) of immunotherapy. Rheumatological irAEs can be of late onset, occur even after the cessation of the culprit drug and persist into time. In this article we discuss the principles of cancer immunotherapy, clinical manifestations and management of the most common rheumatologic irAEs, and aspects of immune checkpoint inhibitors therapy in patients with pre-existing autoimmune disease.
